Abstract

Solid sorbents calcium aluminate-based pellets for CO ₂ capture in chemical looping cycles were studied. The challenges related to loss of carrying capacity of the sorbent and its attrition and elutriation from fluidized bed combustion systems were determined. The use of appropriate binders, particularly, calcium aluminate cement, was necessary. Like other CaO-based sorbents, aluminate-based pellets lost their activity, which is especially pronounced at higher temperatures necessary during sorbent regeneration to produce concentrated CO ₂ streams ready for liquefaction and storage. The results showed the superior performance of aluminate-based pellets, with the added important property that they can be reactivated/reformed, resulting in high average conversions > 35% in series of hundreds of CO ₂ capture cycles. This is an abstract of a paper presented at the 19th International Congress of Chemical and Process Engineering and 7th European Congress of Chemical Engineering (Prague, Czech Republic 8/28/2010-9/1/2010).
